Optimal power flow with environmental constraints using paired bacterial optimizer

Pollution of the power plant has caused harmful environmental effects due to the emission of greenhouse gas. The pollution can be reduced by adjusting the real power outputs of different power plants. However, the relocation of real power outputs results an additional outlay in the system. In order to eliminate the conflict between the cost and emission, an optimal power flow is introduced in this paper, which aims to study the trade-off relationship between the economic dispatch and the power plant emission. Simulation results on the IEEE 30-bus power system demonstrates the perspective of solving the environmental-economic power dispatch problem by a novel optimization algorithm.
